How to solve the problem of aluminum alloy hand plate deformation?
After all, the prototype is only a sample of the product. In the course of use, the influence of excessive external force, temperature, environment and other factors will cause the prototype to crack or deform. How to maintain the aluminum alloy prototype? What kind of preventive measures can better reduce the degree of deformation? How to avoid the entire product from being scrapped due to the deformation of the prototype during the processing of the prototype? The following is a detailed analysis of the deformation of the prototype model. Causes of cracks in aluminum alloy prototypes. Most of the cracks in aluminum alloy prototypes are due to internal stress. When the cracks are greater than the maximum bearing capacity of the prototypes, cracks appear in the prototypes. This is an irreversible loss and should be avoided as much as possible.
Three methods to prevent the deformation of the prototype:
1. To prevent the deformation of the hand plate, it is necessary to make the hand plate uniform in thickness and symmetrical shape in the design. The method of simultaneous solidification is used in the casting process. This reduces the internal stress of the prototype so as to achieve the purpose of preventing deformation; in addition, the deformation prevention measures for the longer-shaped aluminum alloy prototype are anti-deformation measures, and the principle is to eliminate the prototype with the same preventive amount of shape but in the opposite direction. Stress. After the prototype is deformed, there is a certain residual stress inside. The stress should be relieved before processing the opponent board. Stress annealing and natural aging can be used to make internal stress disappear.
2. Most of the hot cracks of the prototype are caused by mechanical stress, which is caused by the solidification of the metal. The solution is to improve the structure of the prototype so that it has fewer surfaces in contact with the metal; the other method is to control the sulfur content of the metal Second, increase the hot brittleness of metals.
3. Prototype cracks are product cracks at low temperatures, which are caused by the deformation of the prototype, and often appear in the stretched area of ??the prototype. The cracks are generally small. When processing large and thin prototypes, cracks often occur. Similarly, the preventive measures are internal stress and control of the phosphorus content in the metal. Prototype is in the process of processing. When processing non-deformed prototypes, experienced prototype personnel are required to better handle the internal stress of the prototype and other factors that cause the prototype to deform. Prototype masters must handle the stress and its balance, adjust the ratio of sulfur and phosphorus in the metal, optimize the structure of the prototype, and reduce the impact of metal heat on the opponent.
